Western Yellowjacket

Vespula pensylvanica


Vespula pensylvanica shares its basic yellow and black pattern with other species of wasp in genus Vespula and its sister genus Dolichovespula which are collectively known in North America by the common name "yellowjacket." V. pensylvanica, however, is the only member of its species group that has a complete yellow eye ring around each compound eye. This eye ring is also visible in queen wasps of this species.

Thank you baamenabar!

Great spotting and great ID, I would have identified as a Vespula vulgaris, (for the pattern on the back), but as you write the yellow eye ring is very characteristic.
